CHURN.

SPECIFICATION forming part of Letters Patent No. 626,623, dated June 6,1899.

Application filed June 25, 1898. Serial No. 684,464. (No model.) 7

To all whom it may concern:

v Be it known that I, MATTIE OMARRoW, of

Paris, in the county of Lamar and State of Texas, have invented a newand useful Improvement in Churns, of which the following is aspecification.

' The object of my invention is to provide a simple and effectivechurn-operating mechanism which does not need any particular form ofreceptacle to hold the cream, but which is designed to be applicable forchurning butter in a bowl, a jar, a bucket, or any other receptacle inwhich the cream may be contained.

A further object is also to provide such a construction as may be easilymade and repaired by any carpenter or farmer without having to rely uponthe manufactories of cities.

My invention operates upon the principle of aerating and cooling thecream at the same time it is being churned and also of obstructing thecentrifugal action of the cream by a breaker; and it consists in thepeculiar construction and arrangement of parts which I will now proceedto fully describe with reference to the drawings, in which Figure 1 is afront view with a stone jar shown in dotted lines as a receptacle forholding the cream. Fig. 2 is a side view. Fig. 3 is a top plan view.Fig. 4 is an under side view of the aerator, and Fig. 5 is across-section of the current-breaker.

In the drawings, A represents a base having short legs or strips Z infront forsupporting it a short distance from the floor or table. 8' Bare two vertical side pieces. 0 is a vertical back piece, and D a toppiece, all of which parts may be conveniently made of wood securelynailed or screwed together. The base A forms a table upon which issupported the detachable receptacle J (shown in dotted lines) forcontaining the cream to be churned. This receptacle may be anearthenware jar, a bucket, pail, tub, crock, or any other convenientreceptacle. The side pieces B B are preferably cut away with asemicircular opening on the side to give more room for the hands inplacing the receptacle J in position or taking it out. The back piece 0has its lower part formed into short legs Z Z and its top part extendedabove the piece D in the form of a handle 0 for moving the churn orsteadying it while'being operated. On the top piece D and in the anglebetween it and the handle 0 is secured a short arm D. The front end ofthis arm is slotted vertically to form a bearing 12, and the front endof top piece D is also slotted verticallyto form a bearing 1), in whichtwo bearings there revolves and is supported from its upper end alone arevolving shaft h, having rigidly attached to the same between the.bearings b and b a grooved pulley G. To the lower end of the revolvingshaft his detachablysecured by a set-screw h an aerator and beater H.This consists of a tapered tube smallest at the top, which is closed,and largest at the bottom, Where it is provided with a horizontal diskK. The tapered tubular portion of the aerator is provided along itssides with a series of curved openings n, having flanged edges, and tothe under side of the bottom of the disk is attached a bridge-piece 0,which is perforated to receive the shaft h and hold the aeratorconcentric. To the under side of the disk there are attached a set ofthree, more or less, revolving wing heaters r and mounted to revolvefreely upon loop-shaped axes 0 extending down from the disk.

I is a vertical shaft extending through a bearing in the top piece D ofthe framework. This has rigidly attached on its upper end, above thepiece D, a grooved pulley m, and below the piece has a detachablecurrentbreaker 1, formed of a V-shaped piece of metal arrangedlongitudinally on the shaft I and detachably connected thereto by a setscrew 2'. This current-breaker, like the aerator, is supported only atits upper end and has no bearing at its lower end, but simply dips downinto the cream to arrest and break up the circular or centrifugal actionof the cream as caused by the revolving beater and aerator.

On the rear side of the vertical back piece 0 of the main frame there ismounted a short axial bearing, upon which is supported and turns a largegrooved wheel E, having a turning crank or handle F. Aroundthe'peripheral groove of this wheel there passes an endless cord or belt25, which passes over two guide-rollers a a at the upper edge of theframework and then extends horizontally around the pulley G of theaerator-shaft, and as it passes around this pulley one side of said beltbears against a pulleym on the currentbreaker shaft I.

The operation of my churn is as follows: Any receptacle containing thecream is placed on the base or table A and the aerator-shaft and aeratorand the current-breaker shaft, with current-breaker, are let down intothe cream. To do this, the set-screw securing the current-breaker isfirst loosened, the currentbreaker inserted in the cream-receptacle,andthe shaft I is then slipped through the top piece D and is thenconnected to the currentbreaker I by means of the set-screw. The

aerator-shaft,with aerator,is inserted into the receptacle and is thenadjusted laterally into the hearings b h, and the belt t is thenextended around the pulley G and in contact with 'm. Now as the wheel Eis turned by its handle F it imparts a very rapid revolution to theaerator and heater, air is distributed through the cream, and therevolving heaters on the lower side of the disk cause a rapid andviolent agitation of the cream,that has a tendency to set it whirling;but this whirling motion is broken up by the rotation of the V- shapedcurrent-breaker I. The general effect is to cause a rapid churning ofthe butter in a very short space of time, producing a high grade ofbutter and a large yield of the same.

Having thus described my invention,whatI claim as new, and desire tosecure by Letters Patent, is

1. Acombined aerator and heater for a rotary churn, consisting of apendent shaft supported Wholly at its upper end and having a taperedtube H with flanged and curved openings in its sides, and having at itsbottom a horizontal disk with bridge-pieces and rotating wing boatersarranged upon horizontal axes attached tothe under side of said disk,substantially as and for the purpose described 2. A current-breaker fora rotary churn consisting of a vertical and pendent shaft supportedwholly at its upper end, and a piece V-shaped in cross-section inclosingsaid shaft and extending longitudinally thereon and means for detachablyconnecting it to the shaft and rotating the shaft, substantially asshown and described.
